I would like to locate sources in order to purchase seeds for Tidwell German, Pink Ponderosa and Riyal Hillbilly, Marizol Red Beefsteak tomatoes. I reside in Livermore, CA and need to know if there strains are suitable for this area? Does this web-site have a sales dept.?
Do a Goggle search for sources.
You can also check Ebay or Etsy, they are often good resources for seeds and plants.
